A heat exchanger is provided. The heat exchanger includes at least two fins set with multiple communicating-groove structures and connecting-groove structure respectively. Each connecting-groove structure has multiple connecting-groove assemblies, and some communicating-groove structures have multiple communicating-groove assemblies. Each groove assembly has multiple groove units. In each fin, a communicating-groove structure is not communicated with a connecting-groove structure, and one communicating-groove structure is not communicated with another communicating-groove structure. When the fins are assembled, a communicating-groove structure of one fin is communicated with the adjacent communicating-groove structure through a connecting-groove structure of another fin. In the invention, the heat-exchange fluid is forced to be confluent or separated constantly when the heat-exchange fluid flows into the heat exchanger. This increases the contact area between the heat-exchange fluid and the heat exchanger substantially, and increases the rate of the heat-exchange process of heat-exchange fluids to achieve good heat-exchange performance. |
